Carbon Monoxide (CO) Testing
Billy Goat Plumbing offers professional carbon monoxide (CO) testing services to ensure your gas appliances and combustion systems are operating safely and efficiently. Our qualified gas plumbers use calibrated analysers to measure CO levels in flue gases, assess combustion efficiency, and identify incomplete combustion or ventilation issues that could lead to dangerous gas build-up. We provide clear diagnostics and practical recommendations such as appliance tuning, ventilation improvements or further safety repairs. We also provide a full report you can keep for compliance and peace of mind.
Fast and reliable Billy Goat Plumbing keeps your home or business breathing easy.

Residential CO Testing
At Billy Goat Plumbing and Gas provide comprehensive residential carbon monoxide (CO) services to the Geelong region that include inspection, detection, source identification, mitigation and ongoing monitoring to keep homes safe and compliant. We use calibrated electronic CO and combined gas detectors to survey living areas, plant rooms (in apartments) and appliance vents. We perform combustion appliance zone testing, flue and ventilation integrity checks, and assess HVAC heat-recovery and duct systems for poor exchange or leaks.
Where elevated CO or poor ventilation is found, we implement corrective measures such as improving mechanical ventilation, repairing or replacing faulty flues, sealing back-drafts, adjusting combustion appliances and installing or upgrading extraction fans or energy recovery ventilators. Post-remediation monitoring includes short-term verification with portable analysers and, where required, installation of wall-mounted CO monitors or data-logging sensors to track trends and alarm thresholds over time; we also offer maintenance schedules and re-testing to ensure ventilation performance remains effective, keeping you and your family safe.
Commercial & Workplace CO Testing
Commercial and workplace carbon monoxide (CO) testing is a regular practice for Billy Goat Plumbing gas plumbers.
We perform systematic monitoring of indoor air to ensure levels stay within safe, regulatory limits and to optimise ventilation for occupant health and productivity.
We deploy calibrated CO sensors at strategic locations like meeting rooms, in open-plan office spaces, kitchens and plant rooms. We conduct spot checks and continuous logging, and interpret data against occupational health & safety standards to identify poor ventilation, occupancy-related spikes or equipment malfunctions.
Where elevated CO is detected, our team diagnoses root causes (ventilation shortfalls, HVAC faults, combustion appliance issues), recommends remedial actions such as ventilation upgrades, demand-controlled ventilation or appliance servicing, and provides clear reporting and compliance documentation to assist building managers in maintaining a safe, comfortable workplace.
Frequently Asked Questions about Carbon Monoxide (Co) Testing
-
Carbon monoxide (CO) is a colourless and odourless gas produced by the incomplete combustion of fuels such as natural gas and LPG. Gas heaters, hot water systems, stovetops, ovens and other fuel-burning appliances can produce carbon monoxide. Problems can arise when an appliance is faulty, poorly maintained, incorrectly installed or does not have adequate ventilation.
-
A range of gas appliances can produce carbon monoxide, including gas heaters, wall furnaces, ducted heating systems, gas hot water systems, stovetops, ovens and decorative gas fires. Regular servicing by an appropriately qualified gasfitter can help ensure appliances are operating safely and identify potential problems.
-
Carbon monoxide cannot be seen, smelled or tasted, so its presence may not be obvious. Professional testing uses specialised equipment to assess appliances and identify potential carbon monoxide or combustion-product spillage. If you have concerns about a gas appliance, stop using the appliance and arrange for it to be inspected by an appropriately qualified gasfitter.
-
Carbon monoxide testing should form part of a thorough assessment of the gas appliance and its operating environment rather than simply taking a CO reading. Depending on the appliance, this may include inspecting its condition, checking ventilation and flue performance, testing for negative pressure and assessing for combustion-product or carbon monoxide spillage.
If a problem is identified, we'll explain what we've found and what action may be required to make the appliance and installation safe.
-
Regular servicing is an important part of keeping gas appliances operating safely. Requirements can differ depending on the property and appliance, so we can advise you on an appropriate servicing schedule.
For Victorian rental properties, prescribed gas safety checks are generally required every two years for applicable rental agreements. From 13 October 2026, this requirement will extend to all Victorian rental agreements, regardless of when they commenced.
-
Yes. We provide carbon monoxide testing and gas appliance safety services for both residential and commercial properties. We can assess gas appliances and their operating environment, identify potential safety concerns and recommend any servicing or repairs required.
